Helping out with a Night Hike at the Texas Butterfly Festival last night, I found this Flattie on one of the attendees. We had a really good time. We saw lots of spiders and I got two new moths species.

Happy All Souls' Day! Continuing with spiders, it's only fitting to post a Ghost Spider.

This is a ghost spider from the genus Hibana. They earned their spooky name from their pale, semi-translucent bodies and their incredibly fast, phantom-like movements.

Happy All Saints’ Day! Saint Felix of Nola, fleeing persecution, hiding in a small opening in a wall. A spider spun a thick web across the entrance, hiding him from pursuers. Because of this miracle, Saint Felix is considered the patron saint of spiders.

Pseudoscorpions are small arachnids that are often overlooked. They prey on clothes moth larvae, carpet beetle larvae, booklice, ants, mites, and small flies. Pseudoscorpions will sometimes hitch rides to new locations on other insects. #Arachtober
A tiny arachnid with a gold body and brick-reddish claws. It is standing on bark that looks like rough sandpaper.

Vinegaroons are arachnids that are not spiders. They have a large pair of pedipalps that are used to catching and crushing prey. They get the name Vinegaroon because they can discharge foul smelling liquid to deter predators. #Arachtober

A large brown arachnid with a stout pair of pedipalps and eight legs, two of which have evolved into sensory whips. It is standing on my hand with desert mountains in the background.

I noticed a quickly shutting tiny door. I pried it open to see this set of legs. Only good shot I got. Possibly a Southwestern Trapdoor Spider (Eucteniza relata). First trapdoor spider I have found. Found in South Texas.

How about some spiky spiders tonight? This one is Micrathena acuta, a spiny orbweaver found in the Ecuadorian Amazon rainforest. It is believed that the spines serve as a defense from birds and even predatory wasps.

Green Lynx Spider (Peucetia viridans) with a moth. I am trying (not very successfully) to not post the same species too often, but I love the depth and detail in this shot so I had to share it. #Arachtober #spider #arachnid #naturephotography #macro #macrophotography #stereography #stereopair

I wish I had better depth on these, but with the cha cha method of shooting stereo, its near impossible because a few are always wiggling between frames.
